Blogging for fun

So I have setup my Blogger and this is my first post. I never thought it could be so easy to open a blog. I need some topic to blog about. What do I choose... have no idea...
First I want to see the look and feel of my blog and see how it looks on the web.

Anyway let me put some content. I had uploaded a fun video of my pet puppy playing which I am embedding below.
